AD5175BRMZ-10-RL7

Overview

The AD5175BRMZ-10-RL7 is a single-channel, 1024-position digital rheostat from Analog Devices. It features a nominal resistance of 10 kΩ with a temperature coefficient of 35 ppm/°C and ±15% tolerance. The device operates on a single supply of 2.7 V to 5.5 V or dual supplies of ±2.5 V to ±2.75 V. It includes a 50-times programmable (50-TP) nonvolatile memory block that retains wiper settings across power cycles. Communication is handled via an I²C-compatible interface supporting standard (100 kHz) and fast (400 kHz) modes. The component is housed in a compact 10-lead MSOP package and is rated for operation between −40°C and +125°C.

Feature Summary

• 1024-position resolution with 10 kΩ nominal resistance
• 50-times programmable (50-TP) nonvolatile memory for wiper retention
• I²C-compatible serial interface with hardware reset capability
• Dual-supply operation support for bipolar signal adjustment

Applications

• Mechanical rheostat replacements
• Op-amp variable gain control
• Instrumentation gain and offset adjustment
• Programmable voltage to current conversions
• Sensor calibration

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging details. The RL7 suffix indicates reel packaging. Confirm availability status through authorized distributors as supply levels may vary. Ensure the selected variant matches the required package type and temperature range specifications.

Selection Notes

Select this component when a single-channel digital rheostat with nonvolatile memory is required. The 10 kΩ resistance value and 1024 taps provide precise analog control. Verify that the system supports I²C communication at the desired clock speed. Ensure the power supply rails fall within the 2.7 V to 5.5 V single-supply or ±2.5 V to ±2.75 V dual-supply ranges.

Part Context

This part belongs to the AD5175 series of digital potentiometers. It is functionally similar to other devices in the family but distinguished by its single-channel configuration and 10 kΩ resistance value. The BRMZ designation identifies the specific temperature grade and MSOP package variant within the product line.

Replacement Considerations

Direct pin-to-pin replacements within the same series include variants with different resistance values or channel counts, such as the AD5171 or AD5172, provided the electrical parameters meet the design requirements. Cross-model substitution requires verification of interface compatibility and memory features.
